1. Glutathione: Glutathione is a powerful antioxidant naturally produced in the body. When used in skincare products, it may help protect the skin against oxidative stress caused by free radicals, environmental pollutants, and UV radiation. Glutathione is also believed to have skin-brightening effects and can potentially help reduce the appearance of dark spots, hyperpigmentation, and uneven skin tone.
2. Glycolic Acid: Glycolic acid is an AHA (Alpha Hydroxy Acid) known for its exfoliating properties. It helps to remove dead skin cells from the surface of the skin, promoting a smoother and brighter complexion. Glycolic acid can also stimulate collagen production, improve skin texture, and reduce the appearance of fine lines and wrinkles.
3. Niacinamide (Vitamin B3): Niacinamide is a versatile ingredient that offers multiple benefits for the skin. It helps to improve the skin's barrier function, regulate oil production, and reduce inflammation. Niacinamide can also help minimize the appearance of pores, even out skin tone, and enhance the skin's natural moisture barrier.
4. Lactic Acid: Lactic acid is another AHA that provides gentle exfoliation to the skin. It helps to remove dead skin cells, improve skin texture, and promote a brighter complexion. Lactic acid can also help retain moisture in the skin, making it suitable for dry or sensitive skin types.
5. Hydrolyzed Collagen: Hydrolyzed collagen is derived from collagen, a protein found in the skin. It is known for its moisturizing and anti-aging properties. When applied topically, hydrolyzed collagen can help improve skin elasticity, firmness, and overall hydration. It may also help reduce the appearance of fine lines and wrinkles.

Combined, these active ingredients in a glutathione cream can potentially provide antioxidant protection, skin-brightening effects, exfoliation, improved skin texture, and enhanced hydration. However, it's important to note that individual responses to skin care products can vary, and results may depend on factors such as skin type, sensitivity, and the concentration of the active ingredients in the product.
